UL Cable Vertical-Tray Flammability Testing Equipment
Product parameter of the UL Cable Vertical-Tray Flammability Test
| Test room | Fire resistance bricks for walls and which density is 1698kg/m3, Interface spray black paint, and the outer size of the room is W2438×D2438×H3353mm |
| Door | Stainless steel frame and wired-glass door, the overall size is W0.9× H2.0m |
| Smoke collection hood | Which made by stainless steel, each side is to be sloped 400, the hood as a cube and each side length is 914mm, there is a dust mesh under the hood and each side length is 610mm |
| Observation window | Which as a square and each side length is 457mm, 1295mm distance from the lower side of the window to floor, 1143mm distance from right of the window to the wall |
| Air inlets | which size are 559×343mm, 914×305mm, 2438×343mm |
| Exhaust duct | L9000×φ406mm, install it at the centered in on the right side of the cube hood |

| Burner | L341mm×D30mm with 242 holes |
| Gas flux | 13.2L/min, 0.1Mpa for gas pressure |
| Flux checking | The differential pressure flowmeter sense smoke pipeline flow speed , provide basis for the control of fan speed |
| Light transmittance | photocell sense the smoke density during the flaming |
| Height of flame | Infrared visible light show the current height of the flame real-time |
| Special software | Draw up the curve by the pip flow, smoke density, height of the flame ,and form a table automatically, through the printer printing |
| Control system | 5.7inch color touch screen, PLC from Japanese Panasonic, SCM, 16 bits high-performance AD transform etc |
Product introduction of the UL Cable Vertical-Tray Flammability Tester
Apply to check the vertical-tray fire test for determining values of cable flame propagation and smoke release when the cables are subjected to a flaming ignition source. (It is nothing to the purpose of cables, such as the electric power, telecommunications etc.)
Main components
Main consist of Ignition source & supply fire control system, collection hood & exhaust duct flux control system, pressure measurement instrumentation of gas, smoke measurement instruments & temperature measurement system, flame height measurement system etc.
Standards
According to the clause 9.6 & 9.7 of UL1685-2007, UL2556-2007
